PIPE-LOADING MACHINE.

To all whom it may concern:

Be it known that I, CORNELIUS JORDAN, a citizen of the United States, residing at Cohoes, in the county 'of Albany and State arrangement of means for automatically and positively forcing fabric over a tube.

Another object of the invention is the arrangement of an improved tube with a plurality of rollers, in combination with coacting rollers for crowding or forcing fabric on the tube. 1

A further object of the invention is the arrangement in a pipe loading machine of means for crowding fabric on the tube and mechanism for turning on and off the power automatically as the means for forcing the fabric over the tube is brought into contact with the tube and removed.

A still further object of the invention is the arrangement in. a pipe loading machine, of friction heads or rollers formed with a plurality of engaging straps, and means for maintaining the same taut.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as. will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a perspective view of an ei'nbodiment of the invention, looking from the front. Fig. 2 is a perspective view of the machine shown in Fig.1, but looking at the same from one side, and showing the friction heads or roll.- ers against the fabric carrying tube. Fig. 3 is a fragmentary scctionalview through Fig. 2, approximately on line 3 3 thereof. Fig. 4 is an enlarged detail fragmentary view of a belt shifting nmchanism, enil'iodying ccrtaiu features of the invention. Fig. 5 is a side elevation of a friction head or roller, together with its driving rod. Fig. 6 is a section through Fig. 5, approximately on Specification of Letters Patent.

line 66 thereof. Fig. 7 is a section through Figs. 5 and 6 on lines 7-7. v Fig. 8 is aside elevation of the fabric carrying tube embodying certain features of the invention.

' Fig. 9 is a longitudinal section through Fig.

, embodying the invention, a tube of any desired dimension is provided and supported at one end in any desired manner. This tube is arranged to have one end positioned between 'a pair of rollers or friction heads for engaging and cooperating with a pair of anti-friction rollers located on the tube for forcing or crowding tubular fabric upon the fabric supporting tube. The friction heads or feeding rollers are formed with ends acted upon by a spring, which normally tends to'force the same apart, and are con nected by strips of flexible material, as for instance a good quality of leather, which are laced through suitable openings in the ends, and form a yielding fabric gripping surface. The strips of leather or other ma terial hold the ends from separating to any large extent under the actionof the spring,

and consequently the spring, by its action, keeps the leather strips taut. for properly acting upon the fabric being forced on the tube.

The friction heads or rollers are slidably mounted upon driving shafts in order to be adjusted to various heights for accommodating the tubes positioned therebetween, and are arranged to be driven by any suit.- able power. The driving shafts for the friction heads or rollers are arranged in pivotally mounted brackets, which may be moved. for forcing the friction heads against or from the tube positioned therebetwoen. Connected with the brackets'carrying the driving shafts of the friction heads is a belt shifting mechanism which will automatically throw the power belt to an idle pulley the tube or pipe, and the friction heads or will be forced or pushed upon the tube by the rotation of the friction heads which do not act directly against the tube, but" co-act with the rollers'on the tube, "so as to force the fabric on the tube and notustrain or stretch the same. After the fabric has been placed upon the tube the same may be withdrawn and dried during'the withdrawing movement by forcing heated air: through the tube, and from thence out through the fabric. Also if desired the heatedair may be used duringthe loading .of the pipe, though ordinarily the same .is not used until the pipe is unloaded. A v

p In order that the invention may be more clearly understood, an. embodiment of the same is shown in the accompanying drawings, in which 1" indicates a base upon which are pivotally mounted supporting brackets 2 and 3, which carry friction heads or rollers 4; and 5. The friction heads or rollers land 5 are bodily movable with their supporting brackets 2 and 3, which are journal'ed. upon;

shafts 6 and 7; so that whensupporting brackets 2 and '3 are movedtoward each other the friction heads or rollers d and 5 will be moved against the rollers 8+8; and 9-9 connected with the tube or pipe 10.,

p In connection with the tube or' fabric supporting pipe; 10, are arranged the rollers S8 and 99, more clearly shown in Figs. 8 to 11 inclusive. Each of the rollers. 88 and 9-9 are constructed preferably of some slightly yielding substance, as for instance, wood, and are each provided with abearing sleeve 11' constructed of metal. Passing through each ofthe sleeves 11 is a bearing shaft 12 which shafts are secured in brackets-13 and 14g Brackets 13 are bolted or otherwise rigidly secured totube or pipe 10 so that the ends thereof projecta slight distance on each side, but the central or body portion thereof is positioned inside of the tube with the ends extending through openings 15 and. 16 Brackets M are bolted or otherwise rigidly secured to pipe '10, but are positioned entirely outside of the pipe, and are arranged to'ihave their ends come opposite the ends (of brackets. 13, so that-the rollers 8 '-8 and 99 may be positioned in openings 15 and .16; The central part of the rollers are .In'cferably arranged; so as to extend equally inside and outside of the pipe, though this position is ,not. absolutely necessary. The brackets 13 and 1.4: are so arranged as to cause the rollers S-Sand to posit1 oned ahnost in contact, as clearly shown in Figs. 8. tolO inclusive; .In

mounting the tube 10 the samemay. be sup ported at or near the end oppo'site the end carrying the rollers 8 ric and the brackets.

v to any desired extent.

and 22 15 provided with notches 32, and cor- S, and 9 4). I The tube 10 isalso arranged so that-the friction rollers 5 and G'when forced against the, tube will ,come between the respective rollers 8-58 and. 9 5,), so as tobearf evenly against all of the rollers, and thuspresent a gripping and feeding device for the fabric that is of maximum efiicieney and causing a minimum am'ount'of strain on the fabric being crowded or loaded upon the machine.

In arranging the friction rollers 4 and 5 and operating mechanism in combination with pipe 10, pipe 10 is arranged with brackets 13'uppern10stas the same are positioned on the interior of the pipe. The brackets 14 being beneath the pipe will not interfere in forcing the fabric over the pipe as the sagging of the .cloth or fabric at this point prevents any interference between the fab:

The friction heads or rollers, :as more clearly seen in Figs. 5, (3 and 7,.are slidably mounted upon driving shafts 17 and 18. Each of the friction heads or rollers is of identical construction, and therefore the description of head or roller 4, withparticular reference .to Figs. 5, 6 and 7 will be ap-' plicable to both rollers.

Roller or head 4: is slidably mounted upon shaft 6, andis designed to be rotated thereby. A key-way 19 is formed inshaft 17 foraccommodating keys 20--20 .rigidly secured to theends 21. 22. By-this means the head or roller may. be moved longitudinally of its driving shaft 17,. but will bealso in connection therewith so as to be always positively rotated thereby. Shaft- 17 is also formed with a plurality of apertures 23 which preferably extend only a short distance into the shaft for accommodating a locking p1n2l which is mounted in a'guide 25 and adapted to freely reciprocate therein. A spring 26.is also mounted in guide 25, and presses a ainst a sto 27 and a ainst one end of pm 24:, so as to normally force the same against shaft 17, "an,d into apertures when the same have come opposite the pin. The bar 28 is passed through pin 24, which acts as a hand-hold, and is designed to be movable in slots 29 with openings 30 and 81 through which the. fingersof an operator may be passed, and pressure appliedto bar. 28 for raising pin 24 out of any of the apertures 28, so as to 1 permit the adjustment of the head or roller Each of the ends 21 .good q1u1lity of leather.- Preferably the strip 35 is su'tliciently long to be vthreaded inand, out for'forming all of theh friction bars Eldon the entiref head, so that-it will 29. -End 22 is formed only. benecessary to, fastenfl the strip or I member 35 together at onepoint.

The ends of the strip 35' are preferably secured together beneath bars 36, so that the fastening means will not come in contact. with rollers 8-8 and 99. In order to hold the bars 36 of the flexible strip 35 taut a spring 37 is provided which surrounds shaft 17, and continuously presses against the hubs of ends 21 and 22 for giving the same a continuous tendency to separate. By this means a friction head is provided that has not only friction bars which are yielding, but also ends that will yield in addition to the bars.

The friction heads 4 and 1' may be freely adjusted on thedriving shafts 7 and 8, so as to permit pipe 10 to be arranged at any height, and also to accommodate any saging in the pipe, either before or after the fabric has been loaded thereon. The driving shafts of the friction heads are pivotally mounted at 38 and 39 in brackets 2 and 3, and extend down from thence, and are rigidly secured to pulleys 40 and 41. Preferably the ends of shafts 17 and 18 extend through pulleys 40 and 41, and rest in sockets in supporting brackets 42 and 43, whereby not only shafts l7 and 18 are correctly held in position, but also their driving pulleys 40 and 41. Passed around pulleys 40 and 41 are blades 44 and 45 which also pass over pulleys 46 and 47 rigidly secured to shaft 48, which is journaled in brackets 49 and 50 at any desiredheight.

Rigidly .secured to shaft 48 is a driving or power pulley 51 which is adapted to be moved by a power belt 52 when the belt has been shifted upon pulley 51. A spider 53 is provided on. shaft 48 and is designed to have automatically shifted thereon belt 52 when the friction'heads or rollers 4 and 5 have been moved to the position shown in Fi 1.

In order to shift belt 52 from pulley 51 to pulley 53, and then back again, a shifting fork or guide 54 is provided which is bolted or otherwise secured to a bracket 55 which is slidingly mounted upon guide Bracket 55 is rigidly secured to reciprocating bolt, 57 which'is guided by a guiding lug 58 through which the same passes. A spring 59 surrounds shaft 57 and'is positioned between lugs 58 and bracket 55, and continuously presses against bracket 55 and lugs 58 for giving bracket 55 a tendency ,at all times to moveover beneath pulley 51,- and thereby to shift belt 52 from pulley 53 to pulley 51. Reciprocating shaft 57 has connected with oneend thereof a cable 59 which passes over a. pulley 60 and from thence over a pulley 61. F rompulley 61 the cable 59 passes over pulley 62, through the guiding U-bolt- 63, and from thence over pulley 64, from which the cable extends back to the U-bolt- 63, and is clamped thereto. between bars (iii-65. Pxulleys 62 wand 64 are pivotally mounted &

upon pins 66 and 67 secured in brackets 2 and 3, so that when the heads 4 and 5 and and 64 will be moved apart, and consequently cable 59 pulled, which will also pull shaft brackets 2 and 3 are moved apart pulleys 62 57 to the position shownin Fig. 3. 'hen pulley 53 to pulley 51.

In order to properly move brackets 2 and 3 and the various mechanism carried thereby a shaft 68 is provided having threaded ends 69 and T0, the threads at the ends being ar ranged as right and left threads, so that when shaft 68 is rotated by hand wheel 71 the brackets 2 and 3 will be moved toward each other, or from each other as the threads are desired to operate in pivotally mounted nuts '72 and 73, which are journaled in supporting members 74, and 75. Suitable slots 7 6 and 77': are provided in brackets 2 and 3 for permitting the reciprocation of shaft 68, and also the swinging or pivotal movement of brackets 2 and 3. Shaft 68 is secured thereto by any desired means, as for instance set screws or sleeves 78 and 79 which may be clamped upon shaft 68 at any desired point for preventing the heads 4 and 5 from being forced too tightly against rollers 8'8 and 9-9. Shaft 68 also carries a guiding wheel 80 which operates in bifurcated end 81 of bracket 82, which .bracket 82 is secured by any desired means, as for instance bolts 83, to the base 1. By the arrangement of slots 84 in base 1 bracket 82 may be adjusted as desired. Guiding wheel or disk 80 is rigidly secured to shaft 68 by any desired means, as for instance by a set screw, and is designed to cause heads 4 and 5 to approach the rollers 8--8 and 99 at the same time, and to prevent the movement of one head and not the other. I

By this construction and arrangement of various mechanism as set' forth, tubular fabric may beloaded upon the pipe quicklyand without straining or tearing the fabric. Also it will be observed that by the operation of hand wheel the machine will automatically stop or start according to where the friction heads or rollers 4 and 5 have been moved. the friction heads during operation are self-tightening for accommodating variousstrains. Another important point is the arrangement ofithe hand wheeland surrounding parts in its'particular association with the friction heads and connecting parts, whereby positive means for closing the friction heads. or rollers against the tube at any required pressure is provided.
